FUSE HOLDER.

Application filed August 24, 1925. Serial No. 52,038.

This invention relates to new and useful improvements in fuse cartridgesand has for its primary object the provision of novel means forremovably applying and clampmg a fuse within the cartridge without theuse of tools.

A further object is the provision of novel means associated with theends of the cartridge for protecting the insulator body of the cartridgeas well as for effectively clamping the fuse in the said ends of thebody.

A further object is the provision of a dev ce for this purposecharacterized by simplicity in construction and reliability andetliclency in practical use.

To the attainment of the foregoing, the invention consists in theimprovement as hereinafter described and definitely claimed.

In the drawings Figure l is a side elevation of the improvement.

Figure 2 is a central longitudinal sectional view of the invention.

Figm'e 3 is an end view of the body of the improvement, the wedgecarrying contact and the cap being omitted.

Figure 4c is a view looking toward the inner end of the cap.

Figure 5 is a side elevation of the cap.

Referring now to the drawings in detail, the numeral 1 designates thebody of the improvement. The body is in the nature of a tube of fibre orother insulating material. Fixed, by means 2, in the ends of the bodythere are metal blocks 3 which are round in cross section and which areprovided with lon gitudinal ports 4 which admit air into the body 1. Theouter port-ion of each block 3 is threaded, as at 5, and each block isprovided with a wedge-shaped opening, the lower wall of which beingflat, as at 6, and the upper wall arched and flared inwardly, as at 7.The ends of the fuse 8 rests on the shoulders provided by the walls 6 ofthe wedge-shaped openings in the blocks 3.

Designed to be screwed on the metal blocks 3 there are cap members 9.Revolubly arranged in each of the cap members there is a disc head 10carrying on its inner face a wedge 11 complemental in shape to the walls6 and 7 provided by the wedge openings in the blocks 3. The head 10 isheld on the outer flange of the cap nut 9 by a ring 12, removable means13 holding the rin positioned. This prevents the independentlongitudinal movethe metal wedge members 11 are influenced by thescrewing of the cap nuts 9 to wedge engagement with the fuse blade 8.The con: struction is simple and is practically indestructible and theadvantages thereof will, it is believed, be perfectly apparent to thoseskilled in the art to which such devices relate, when the foregoingdescription is read in connection with the accompanying drawings.

Having described the. invention, we claim A fuse holder, comprising afibre tube, cross sectionally rounded metal members let in, secured tothe ends of said tube and projecting beyond said ends, each of saidmembers having an opening therethrough whose inner wall is fiat andWhose opposite wall is round and flared from the outer to the inner endof the said member, the fiat walls of the said openings designed toprovide a rest for the ends of a fuse, metal disc heads having lugscomplemental to the shape of the openings in the said members anddesigned to be received therein and to have their flat surfaces rest onthe fuse, flanged screw caps arranged around the discs and threadedlyengaging with the projecting ends of the metal members, and designed,when screwed on said members to force the lugs into frictionalengagement with the walls provided by the openings in said members andwith the ends of the fuse ring members in the caps holding the discheads against the flanges of said caps for preventing the independentlongitudinal movement of the caps and disc heads and permitting theturning of the caps on the disk heads, and said metal members and saiddisk heads having ports for admitting atmospheric air into the tube.

In testimony whereof we aifix our signatures. v

CHARLES A. TOZER. PHIL HUNTER.
